Modern mobile phones are updated very quickly. Whenever a new model appears, it is time for many people to prepare to change their mobile phones! After the new mobile phone is available, what is the use of the eliminated old mobile phone? Give people away, others may not value it; It’s a pity to sell second-hand. Today, Xiaobian of Life Coup Network will recommend some wonderful ways to use old mobile phones, so that “former partners” can continue to play their residual heat!
1. Car navigation
A navigation is the cheapest and costs several hundred yuan. If you have an old mobile phone with a 3.5-inch screen and GPS function, you can have a car navigator for tens of yuan by buying a car bracket and a cigarette lighter power plug.
Install mainstream free navigation map applications on your mobile phone, such as Baidu map and Gaode map. As long as you download the offline map in advance, you can help you navigate accurately even if you are not online.
2. Driving recorder
For car owners, the most annoying thing is to encounter an accident dispute, and the driving recorder can truly record the images during driving, so you are not afraid of being wronged when an accident occurs.
It’s just that there are thousands of driving recorders in the workshop, but it only takes tens of yuan to transform with the old mobile phone, which can be said to be a big difference ~ In the old mobile phone, just download the driving recorder app, then use the car bracket to fix it and connect it to the power supply, and you can use it. Powerful, it can support cyclic video recording and power-on automatic video recording, which is not much different from special driving recorder.
3. Home Monitor
Home cloud monitoring equipment can be used to monitor the situation at home, check children and pets, and prevent accidents.
However, a set of cloud monitoring equipment is not cheap. If you happen to have an idle smart phone, you can realize remote monitoring through it. As long as you download the monitoring software on your mobile phone and connect it to the screen of another mobile phone through WiFi, the old mobile phone can be placed as a monitor at home. Being far away, you can have a panoramic view of your home!
4. Universal remote control
Television, electric fans, air conditioners and other electrical appliances all need remote controllers. If you don’t want to worry about a lot of remote controllers, and the old mobile phone just has the infrared emission function, you can completely turn it into a universal remote controller to control large and small household appliances.
For example, the application of “Remote Control Wizard” can realize this function. After downloading the software, first look up the product model of the remote control device (which is commonly found in household appliances), and then let the mobile phone learn to control household appliances through the “learning” program. If you are not at home, you can also realize remote control.
5. Document scanner
Scanning text into a computer for editing can save a lot of typing time, but what if there is no scanner? Is there nothing you can do? NO！ As long as there is a mobile phone that can take pictures, this problem will be solved.
Download mobile apps such as DocScan and Scan Almighty King, and you can convert the screen into text. If you usually have a lot of files to deal with, turn your old mobile phone into an office assistant!
6, mobile phone camera
Of course, taking photos is indispensable to record the beautiful moments of life. Although the pixel of mobile phone has been improving and the photo effect is good, it is still far from SLR cameras. However, it is very cumbersome to carry one eye at ordinary times, so can an old mobile phone be transformed into one eye?
It is not difficult to change the mobile phone into a SLR. Just add an adapter and install a SLR lens, and you can have a simple version of the monocular camera immediately, which is much lighter, but the photo effect will never let you down ~
You don’t need it yourself, you can also give it to your family for use and go out to play, so that children can also record wonderful moments!
7, burglar alarm
Although the public security in most areas is very good now, there are also many people who behave like thieves and chickens. Installing an alarm indoors/in the car is equivalent to an extra layer of protection. This function can be realized by slightly modifying the old mobile phone.
The self-made mobile phone burglar alarm system consists of infrared detector, mobile phone number confirmation circuit and dialing circuit. First, the mobile phone number is stored in the modified mobile phone. When a bad person enters the house or the car is started, the system will dial the entered phone number in real time to remind you to take preventive measures.
8. File storage
Music, movies, games … I can’t bear to delete any of them, but the storage space of the mobile phone lights up. What should I do? At this time, the old mobile phone can come in handy.
Nowadays, mobile phones generally come with 8 GB ~ 32 GB of built-in storage, which can not only save files, such as songs/movies/games, but also be used in real time (watching TV and playing games …). Is it much more practical than mobile hard disks? Of course, if you don’t think your own memory is enough, you can also install a memory expansion card.
In addition to the above methods, you can also use your old mobile phone as an alarm clock, flashlight and audio-visual player. In fact, the old mobile phone is more valuable than we thought!
